SVG import not showing up,why?
Usually when you import a SVG file it is extremely small (so small you cant see it). Draw a box select ("B", or choose it from the outliner) around the center of your screen and scale it up by a lot (You still may not see anything, scale it up again) after scaling two or even three times you will start to see it. 

After you get it to the size you want dont forget to apply the scale (CTRL+A) "apply scale"
